Groundwater is an essential and vital component of our life support system where it is used for drinking, irrigation, and industrial purposes. Wadi Sayyah is one of the most important wadis in the western part of Saudi Arabia to the northeast of Jeddah city. A total of 42 groundwater samples are collected from hand dug wells in this area and they are analyzed for various physical and chemical par ... read more >>
1. 200 billion cubic meters of groundwater, being recharged at a rate of 1.2 billion cubic meters a year, was discovered in Turkana, the poorest and most arid county in Kenya using technology that interprets ground-penetrating radar from satellites.
2. Kenya is categorized as a “water-scarce country” by the UN, with 17 million people lacking access to safe water. The new discovery has the poten ... read more >>

A team including Dalhousie University Oceanography Professor Helmuth Thomas and recent Dalhousie Oceanography PhD graduate Elizabeth Shadwick found evidence suggesting that the Arctic Ocean is more vulnerable to human-induced changes than the Antarctic Ocean. After comparing sites in both oceans, they found the Arctic site to be more acidic, warmer during the summer months, and have fewer nutrien ... read more >>
The reflectivity of Arctic sea ice, or albedo, regulates the solar radiation balance. A diminishing albedo affects the melt rate of Arctic sea ice.
According to a study done by the Finnish Meteorological Institute, the albedo (reflectivity) of Arctic sea ice has declined over the past three decades. The study was published in the journal Nature Climate Change on 4 August 2013. During summer mont ... read more >>
For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher latitudes, particularly the polar regions.
The Northern Hemisphere's last ice age ended about 20,000 years ago, and most evidence has indicated that the ice age in the Southern Hemisphere ... read more >>
